Hybrid Tea rose plant named ‘Twoagain’

ABSTRACT

A new rose cultivar of the Hybrid Tea class characterized by having two to three clusters at one time of large scarlet flowers, each cluster having 8 to 12 flowers, on a very vigorous healthy plant. This plant is marketed in the U.S. as: Dream Scarlet.

The present invention relates to a new and distinctive cultivar of rose plant (Rosa hybrida) of the Hybrid Tea class, which was originated by my crossing ‘Karma’ as the seed parent with the pollen parent an unknown seedling.

Among the novel characteristics possessed by the new cultivar which distinguish it from:

(a) All other cultivars of which I am aware are: (1) Mature plants have 2-3 basal canes with clusters of 8-12 large flowers. (2) Flowers almost continously. (3) Scarlet, non-fading red flowers. (4) Tall vigorous healthy bush.

(b) Seed parent: Semi-double, medium red. Pollen parent: Unknown.

Asexual reproduction of the new rose cultivar by budding, as performed at Wasco, Calif., shows that the aforementioned and all other distinctive characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows typical specimens of the vegetative growth and flowers of the new cultivar in different stages of development and as depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new cultivar, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color description herein refers to plate numbers in the aforementioned color chart, e.g. “53A” is plate “53A” of The Royal Horticultural Society Colour Chart.

Parentage:

Seed parent.—‘Karma’ aka ‘Pounder Star’ (not patented).

Pollen parent.—Unknown.

Class: Hybrid Tea.

The following observations are made of specimens grown outdoors in Monterey County, Calif., in the month of September.
